Large capacity layered microwave radiation extraction device

The utility model provides a large capacity layered microwave radiation extraction device. The device comprises a stirring mechanism, a refluxing mechanism, a feeding inlet, a slag-discharging hole, a liquid inlet pipe, a liquid outlet pipe and a microwave source, and an extraction pot is used as a microwave resonator. The extraction device is characterized in that layered waveguide tubes are arranged in the extraction pot in intervals, the microwave ends of one or more of the waveguide tubes is fixed on the outside of the pot, each microwave end is provided with a magnetron, and the other ends of one or more of the waveguide tubes extends in the pot and is provided with a feed hole. The utility model adopts a plurality of middle and low power magnetrons and uses the microwave incoherent power synthesis theory to perform layered radiation (heating) to the extraction material, thus realizing microwave radiation with low cost and large power and ensuring uniform microwave radiation in the large capacity pot.
